Auxiliary Input Function
The Auxiliary Input allows activation by an external source of either the Horn or
the Manual push-button functions when the rotary s elector switch is in the Manual,
Alert, or Hands Free (HF) position. This input is usually wired into the vehicle horn
switch. The wiring diagram on page 10 shows two connection examples. NOTE:
Permanent disconnection of the vehicle horn is NOT recommended.
The siren is factory shipped with the auxiliary input option defaulted as the Horn
function. To utilize the auxiliary input as the Manual function instead of the Horn
function, remove the third option jumper from the back of the control head. (See
diagram BELOW).

Two-Tone
Two-Tone can replace functions with Phaser by removing the fourth option
jumper from the back of the control head. (See diagram below).
